Note 1. Cable selection conditions: three cables per bundle at 40 _C ambient temperature with the rated current flow-
ing.
2. Use cable with 600 V min. withstand voltage for main circuits.
3. Consider allowable current reduction ratio if cables are bundled in PVC or metal ducts.
4. Use temperature-resistant cable under high ambient or panel temperatures where normal vinyl cables rapid-
ly deteriorate.
